Abstract

The invention discloses a dual-tower dust removing desulphurization device which comprises a main tower. A flue gas inlet is formed on the main tower, a sprayer is arranged on the top side of the main tower, the upper end of the main tower is sealed, a liquid discharge hole is formed at the lower end, twin towers are inserted to the bottom part in the main tower from the upper end of the main tower and provided with communicating holes to communicate with the main tower, the upper ends of the twin towers communicate with a top tower, a sub-tower sprayer and a sub-tower defogger are arranged in the twin towers, a top tower sprayer and a top tower defogger are arranged in the top tower, and a flue gas outlet is formed on the top tower. The dual-tower dust removing desulphurization device has the following advantages: as the dual-tower dust removing desulphurization device adopts the structure of twin towers, the dual-tower dust removing desulphurization device can carry out the dust removing desulphurization treatment of flue gas emitted by a large-scale coal-fired boiler, the dust removing desulphurization efficiency is high, the coal-fired flue gas after the treatment can achieve the requirements of the environmental protection emission; furthermore, the structure is simple, the operation cost is low and the environmental protection benefits are very good.

Description

Dual-tower dust removal and desulphurization device
Technical field
The present invention relates to a kind of flue-gas dust-removing and desulfurization device.
Background technology
China is a coal-fired big country, annual flue dust of discharging from various coal-burning boilers has tens million of tons, these dust-laden sulfur-containing smoke gas without any processing directly are discharged in the atmosphere, are the oxysulfides that contains in the main cause that causes atmosphere pollution, particularly coal-fired flue-gas, be discharged in the atmosphere, combine with vapor in the atmosphere, form acid rain, contaminated land, the water source, cause serious destruction for industrial or agricultural and ecological environment, also endanger the healthy of people.At present, there is following shortcoming in the dust-removing desulfurating apparatus to coal-fired flue-gas both at home and abroad: the one, and complex process equipment, cost is higher; The 2nd, dust-removal and desulfurizing efficient is not high, only is applicable to middle and small burn coal boiler; The 3rd, the operating cost height is unfavorable for promoting the use of.
Summary of the invention
The dust-removing desulfurating apparatus that the purpose of this invention is to provide a kind of large coal-fired boiler.
The objective of the invention is to realize in the following way: a kind of dual-tower dust removal and desulphurization device, comprise king-tower, gas approach is arranged on king-tower, spray thrower is arranged in the king-tower top side, the king-tower upper end closed, there is outage the lower end, and Petronas Towers is inserted into the king-tower inner bottom part from king-tower upper end, and has intercommunicating pore and communicate with king-tower, the Petronas Towers upper end is communicated with head tower, sub-tower spray thrower and sub-tower demister are housed in the Petronas Towers, head tower spray thrower and head tower demister are housed in head tower, head tower has exhanst gas outlet.
The present invention has following beneficial effect, owing to adopt the Petronas Towers structure, can carry out dust-removal and desulfurizing to the large coal-fired boiler discharged flue gas handles, dust-removal and desulfurizing efficient height, treated coal-fired flue-gas can reach the requirement of environment protection emission, and simple in structure, operating cost is low, and good environmental benefit is arranged.
